Is bug in contains polygon ?

[Vladimir]

Hello,

I am beginner in phaser that is why I can missed something.  

 

Please look at Polygon Contains example. 

 

If you change following code:

graphics = game.add.graphics(0, 0);

for example 

graphics = game.add.graphics(300, 100);

But the polygon points the same. You will see that contains polygon is not work.
